Miley Cyrus / Hannah Montana- One in a Million
Before achieving huge success in her own right, Miley Cyrus played the title role in the Disney Channel sitcom 'Hannah Montana' - which followed the adventures of a schoolgirl living a secret double life as a pop star - and, as her alter-ego, released the ballad 'One in a Million' as part of the show's second soundtrack. But while it became a hit for Miley's wig-wearing alterego (pictured), it had in fact been recorded by Sandy Mölling for her debut album some four years earlier.
